• intima-media thi
  • In the carotid artery, intima-media thickness (IMT) was recorded together with an assessment of echogenicity by the Grey scale median (GSM) method in both overt plaques and in the intima-media complex (IM-GSM). (diva-portal.org)
  • Aims: To investigate the association between intima-media thickness of brachial and common carotid arteries and factors of the coagulation- and fibrinolysis system with diastolic dysfunction in patients with a previous myocardial infarction. (uio.no)
  • Pulse
  • Additional symptoms for brachial artery obstruction include sensitivity to cold, discoloration as fingers turn pale or blue, lack of pulse in the wrist, bluish or slow-growing finger nails, arm hair reduction, and a loss of muscle strength. (azcentral.com)
  • Measured by the Doppler wand, the inflation continues until the pulse in the artery ceases. (wikipedia.org)
  • When the artery's pulse is re-detected through the Doppler probe the pressure in the cuff at that moment indicates the systolic pressure of that artery. (wikipedia.org)
  • In a normal subject the pressure at the ankle is slightly higher than at the elbow (there is reflection of the pulse pressure from the vascular bed of the feet, whereas at the elbow the artery continues on some distance to the wrist). (wikipedia.org)
  • systolic
  • OBJECTIVE: Cardiovascular (CV) risk relates to the blood flow velocity pattern in the brachial artery during hyperemia, especially to the hyperaemic systolic to diastolic mean blood flow velocity (SDFV) ratio. (diva-portal.org)
  • Thereafter, artery will be occluded by cuff inflation to 50 mm Hg above systolic pressure for 5 minutes and subsequently deflated. (clinicaltrials.gov)
  • The higher systolic reading of the left and right arm brachial artery is generally used in the assessment. (wikipedia.org)
  • A B P I L e g = P L e g P A r m {\displaystyle ABPI_{Leg}={\frac {P_{Leg}}{P_{Arm}}}} Where PLeg is the systolic blood pressure of dorsalis pedis or posterior tibial arteries and PArm is the highest of the left and right arm brachial systolic blood pressure The ABPI test is a popular tool for the non-invasive assessment of PVD. (wikipedia.org)
  • atherosclerosis
  • Arm artery disease is a form of peripheral artery disease (PAD) and occurs when an arm artery is obstructed, usually a result of the condition known as atherosclerosis. (azcentral.com)
  • Provided that there are no other significant conditions affecting the arteries of the leg, the following ABPI ratios can be used to predict the severity of PAD as well as assess the nature and best management of various types of leg ulcers: Studies in 2006 suggests that an abnormal ABPI may be an independent predictor of mortality, as it reflects the burden of atherosclerosis. (wikipedia.org)
  • Arterial
  • But unfortunately these volume changes are not linearly correlated with the arterial pressure- especially when measured in the periphery, where the access to the arteries is easy. (wikipedia.org)
  • These volume changes must be transformed into pressure, because of the non-linearity of the elastic components of the arterial wall as well as the non-elastic parts of the smooth muscles of the finger artery. (wikipedia.org)
  • The method is to unload the arterial wall in order to linearize this phenomenon with a counter pressure as high as the pressure inside the artery. (wikipedia.org)
  • However, ABPI has known issues: ABPI is known to be unreliable on patients with arterial calcification (hardening of the arteries) which results in less or incompressible arteries, as the stiff arteries produce falsely elevated ankle pressure, giving false negatives). (wikipedia.org)
  • doppler
  • Doppler recordings of blood flow velocity during hyperemia were analysed in the brachial artery. (diva-portal.org)
  • Ultrasonographic doppler measurements of the Brachial artery were made on the 1016 men and women aged 70 included in the prospective investigation of the vasculature in Uppsala seniors (PIVUS) study. (diva-portal.org)
  • endothelial
  • Coronary endothelial function has been shown to improve under lipid-lowering and antioxidant therapy, but the effect of additive vitamin E supplementation in the brachial artery is unknown. (onlinejacc.org)
  • For people who suffer with endothelial dysfunction, their arteries are unable to dilate correctly for many different reasons. (wikipedia.org)
  • peripheral
  • Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD). (wikipedia.org)
  • An ABPI value of 1.3 or greater is also considered abnormal, and suggests calcification of the walls of the arteries and incompressible vessels, reflecting severe peripheral vascular disease. (wikipedia.org)
  • When an arteriovenous fistula is formed involving a major artery like the abdominal aorta, it can lead to a large decrease in peripheral resistance. (wikipedia.org)
  • dilate
  • Depending on how much blood is flowing through an artery at a particular point, the artery must be able to dilate or constrict to allow sufficient blood flow. (wikipedia.org)
  • This is very important at the focal points of circulation where there is lots of blood flowing at one point so it is important for the arteries to dilate. (wikipedia.org)
  • Primarily
  • The Baylor College of Medicine says "Arm artery disease primarily affects cigarette smokers and people older than 60. (azcentral.com)
